If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
Power = Work divided by seconds.or in other words....Power = work/seconds.Clear explanation: Power is equal to:How much work is done (in joules) divided by the seconds of how much time did the work took.For example:Problem: A construction worker pushes the wheelbarrow with the power of 50 J per 2 seconds how much power does he use?Answer: 50 J divided by 2 s is 25 W so, the power is equal to 25 watts.

If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
7.5 watts
Power = 200*9.8*40/40 Watts = 1960 Watts.
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
